Features and Benefits:	Fluorescent probe for the estimation of the CMC of surfactants.
General description:	ANSA (8-Anilino-1-naphthalenesulfonic acid) is a hydrophobic polarity sensitive fluorescent dye useful as a site probe to detect conformational changes in cell and micelle membranes and molecules such as proteins. ANSA is also used as a fluorescent probe for the estimation of the critical micelle concentration (CMC) of surfactants.
